' This inventionv relates t cartons and particularly to cartons providedwith an inner It is desirable, when packaging a largeF variety of oilymaterials such as cloves, cinl namen, spices and the like, and whenpackaging candiesfconfections, etc., to .provide the carton with aninner( lining such as a cellulose parchment liner, or. one formed ofsome suitable non-absorbent material. t This lining prevents the oilfrom .striking through or impregnating the carton walls and renderingthe package unsightly and unsaleable. ItV

also prevents sugar-coated products from` -ilexible walls, will notreadily conforman remain in contact throughout its extent wit l theinner walls of the carton while empty and during the filling operation.-

In" the interval in which the lined carton is being conveyed from thecarton-maklng Amachine, as by endless belt or chaln, to the point wherethe material is automatically fed l by suitablemechanical` means yintothe same, the walls' of the liner are frequentlyexed .or-'warped wayfrom the walls of the sur-v rounding carton, with the result that apor-1 tion of the materials is deposited 'orlled 1n the spaces :thus4afforded'between the l1ner L and'the carton; Also, inl manypinstances,this .warping of the liner -walls occurs during the illingoperation andafter a small portlon A distribute the` materia1s^in equal quantities--of the walls)of the same, and the contents .are partly: discharged' intothe spaces thus formed between the lateral walls of the liner and thecarton. Conse uently, the advantages ,to be obtained by t e use of aliner are ...destroyed and frequentwfthevolume ofthe containerismaterially ecreased.

rIt has been proposed to paste the liner to the carton blank entirelyalong the length' thereof so that the two elements `may besimultaneously :t'olded into box-like form, to-

overcome the highly undesirable e'ects resultlng from warped or inwardlybulging walls. When this is not done, the disadvantages setforth havebeen experienced unless the lined cartons werelled manually, or soslowly as toinsure the reception of the entire' charge within the liner,which, in either case, results in a loss of time, or in increased ex-Apense, or both. Y f

Anl objectof thisinvention is to provide, as an article of manufacture',a simple, inexpensive, linedl carton such that the walls of the .linerwill not warp or become distorted either prior 'to or during the fillingoperation, a

sma'll horizbntal strip, or-strips of adhesive to the linerl or. cartonadjacent the line of fold of the top aps prior Ato the association ofthe linerwith the carton, 'in such a manner that the liner will besecurely held, when installed, in contact with the inner Walls ofthecarton during" the illingvoperation. y

one which may be machine-filled, l1f desired, withoutnecessitating theusepof a funnel and this isv efectedxby applyiig al The invention willbemore readily under- 1 stood byv reference" to the drawings, in whiche' Fig. 1 isa view', in perspective, illustrating one .embodiment of thepresent invention;

Fig. 3 is a view, in perspective, 'illustrating accompanying completelyassociated with the carton Fig. 4 is a sectionalview, on a reducedscale, taken`on .line 5--5 of Fig. 2;

Fig. 5 isa view similar to Fig. 4 illustrating the adhesive materialapplied to the carton'` rather than the liner; and' I Fig. 6 isv aview.\similar tov Figs. 4 showing the manner in which walls of the 9o ofthe, contents has been directed into v the fthe carton andllner beforethe latter has been A y f "lined carton, since it is impossible t9initially n, A liner 8, formed in an ordinary liner warp or bulgeinwardly priorV to and during the filling operation. Referring to theaccompanying drawings, I wherein like reference numeralspindicate like45 parts, 1 is avl carton, preferablyfformed by isuitable machinery froma singlefblank into any desired shape and siz'e,=,ffpr`ovided'withscoring lines 2, 3, 4, etc., cutti g vlines 5, and i Vlapsand 7. f

4sired manner from a suitably shaped blankl of vcellulose parchment orother suitable material, isern- '-ployedas the inner member'of myimproved carton. The sizeof the liner blank is sub- -"stantial1y-thesame as the s1ze of the carton blank in order to provide foldableportions "at opposite extremities of the liner, and said foldable`port-ions" of the liner are entirely 4 `free with respect to thefoldable p/rtions or flaps of the carton (Figs. 1 and 2), in order to:facilitate sealing of the package after the same has been filled.Preferably, I apply a narrow strip 9, o'f `glue or paste, to each o fside walls 1() of liner 8 in such a position that, when the liner iscompletely associated with carton 1, strips 9 will be closeladjacent,but

" below, and substantially paral el to the u per end'o. side walls ofcarton lor'scoring'- ines 3. Since the liner ina carton always engages20 the carton tightly adjacent unfold lines of its sides, it is notessential in overeoming` bulgingof the liner to extendV strips 9 thefull width of the side walls 10 ofthe liner. As shown in Fig. 1, strips9 terminate at both ends within the area defined by scoring lines f 3and 4 and in this manner a. great saving of adhesive is efected. Ifdesired, strips 9 may be applied in any suitable manner to the inner x'side walls of/the carton in the same relative position, i. e. adjacentto, but'slightly below, and substantiall parallelto scoring lines 3, asindicated in 5. t

When my improved carton is formed and assembled by machinery now in useand par- ;.45 ticularly adapted for such work, the cartons and linersare formed and one end'thereof closed andl sealed after the assembly ofthe two members. Adhesivestri s 9'are applied tothe liner 8. or thecarton bei) 5 associated. yAny suitable means may Ythen be employed to'insure. "that the" glue or paste:

- strips shall cause theliner'to adhere to the "walls of the carton or,if: desired, the two cent said s'trrps. Fi 1 and 2 ustrate the ly. Y 4

resultsof this assem Y'When my improvdcartonisbeing con-'c veyed tothefilling point and during the {ill- I; ing` operation, liner 8 is held inclose contact #with the inner walls Aof carton as indicated in Fg.l4`with the result that it is impossible forsmall particles of the materialbeing packaged to fall or enter'between the respecp C5 tive'walls'of thetwomembers forming the' chea ,simple and e ldisa vantagesand objectionsthat are heretoo re the two are container. I thelby prevent the warpingor inward bulgin of the walls of theliner, as illustrated in ig. 6` andthus obviate in a lfective manner the great fore stated. f

The cartons `normally in use are of such size that it isY ordinarilyunnecessary to apply the adhesive strips 9 in any other manner thandescribed and illustrated.

However, in unusually large cartons, it may be desirable to-eXten'd thestrip ofadhesive around the four sides ofthe carton to insureagainst theformation of the objectionable spaces 11.

The invention is capable. of receiving a variety ofexpressions, one.of'which. is illustrated in the accompanying drawings, but

it is to be expressly `understood that the dra.w.- v i ings are forpurposes of illustration onl and are not designed as a definition of the'mits of the invention, reference being had for this- I.

' purpose to the appended claim.

Whatis claimed iszl A carton vcomprising an outer memberA of cardboardor the like provided at the upper end thereof withpackage-closin'giortions extending from four side' panels o ber, and La"separately formed, liexible paper liner adapted' to be assembledtherewith and having restricted adhesive areas adapted 'to attach lit tothe outer member on two opposed top portions only of-'saidmember'andhaving "a body portionin the outer member substantially free of thewalls thereof, s aid liner hav inga ackage-elosing portion adjacent toand entire y free from the package-closing portions on the outer memberand adapted for independently reclosing when portions of the contentshave been removed. i L

In testimony vwhereof I have signed this specification. 'C
